Faxon Firearms
The Faxon Firearms Match Series 7.5" 300 Blackout 5R Stainless Barrel delivers precision and balance in a short-action platform. Built around a 1:5 twist rate—faster than the 1:7 and 1:8 standard in most 300 BLK rifles—this barrel excels at stabilizing a wider range of projectiles and maximizing energy retention downrange, whether you're running supersonic or subsonic loads. The 7.5-inch length is ideal for short-barrel rifles (SBRs), pistol-caliber builds, and handy defensive or hunting rigs where maneuverability matters.
What sets this barrel apart is Faxon's Gunner profile: a hybrid design that marries the proven durability of a full-profile GOVT/SOCOM barrel with the weight savings and balance of a lighter pencil profile. The result is a rifle that doesn't fatigue your shoulders or arms during long training sessions, hunting days, or range time. By shifting weight forward-to-back toward your body, the Gunner profile improves handling without sacrificing the strength needed for reliability and consistent accuracy.
Every Faxon Match Series barrel starts with 416-R stainless steel, receives 5R rifling for superior accuracy and easy cleaning, and includes an NP3-coated barrel extension for durability and smooth operation. Manufacturing happens in-house in Cincinnati, Ohio, with stress relief, air-gauge testing, and a precise 11-degree target crown baked into every step. Each barrel is Magnetic Particle Inspected (MPI) and individually headspace-checked using custom-hardened gauges before shipping, so you know you're getting a production-verified component ready to drop into your build or upper assembly.
Faxon barrels represent genuine value: American-made, thoroughly tested, and backed by a manufacturing process that doesn't cut corners on accuracy or longevity.
| Barrel Length | 7.5 inches |
| Caliber | 300 Blackout |
| Twist Rate | 1:5 |
| Rifling | 5R |
| Material | 416-R Stainless Steel |
| Barrel Extension | NP3 (Nickel Teflon) Coated |
| Crown | 11-degree Target |
| Profile | Gunner |
| Inspection | Magnetic Particle Inspected (MPI), Headspace Verified |
Yes, this is a standard AR-15 pattern barrel. It will fit any AR-15 upper receiver and work with any 300 Blackout bolt carrier group. The 7.5-inch length is legal for most uses (check your local laws); if you plan to use it in a short-barrel rifle configuration with a stock, ensure you're in compliance with ATF regulations.
The 1:5 twist rate spins the bullet faster, which stabilizes a broader spectrum of 300 Blackout ammunition—from light, fast supersonic rounds to heavy, slow subsonic loads. If you run a variety of ammunition weights or shoot subsonics through a suppressor, the faster twist provides more consistent accuracy and reliability.
Yes. The faster 1:5 twist and 7.5-inch length both favor the effective subsonic performance that 300 Blackout is known for. The Gunner profile also keeps the rifle balanced and maneuverable, which is a plus in close-quarters or hunting scenarios where you might run a can.
The Gunner profile is lighter than a full government profile but stronger than a thin pencil barrel. This hybrid design shifts the rifle's balance toward your body, reducing fatigue during extended shooting, training, or hunting. You get better handling without sacrificing durability.
